A series of guanylhydrazones derived from 2- and 4-pyridine and 4-quinoline carboxyaldehydes was synthesized from S-methylisothio-semicarbazide hydroiodide using known procedures. The compounds are analogous to anticancer and antiviral thiosemicarbazones, but several of the guanylhydrazones derived from 4-quinolinecarboxaldehyde showed no activity against P388 lymphocytic leukemia in mice.

The synthesis of some novel (substituted) guanylhydrazones of isatin, 5-methylisatin and 1-methylisatin is decribed. Moreover, detailed nmr-spectroscopic studies (1H-nmr, 13C-nmr) with these compounds and previously known congeners are presented.
A new and distinct
Paeonia
cultivar named ‘RTPIV791-01’ is disclosed, characterized by distinctive creamy pale yellow suffused with pink, fully double, mildly fragrant flowers. Plants are vigorous and symmetrical with strong stems holding flowers above foliage, and with attractive foliage through the Fall. The new cultivar is a
Paeonia
hybrid suitable for ornamental garden purposes.
